Improving participation of under-represented minorities in breast cancer therapeutic trials in a safety-net system.

Abstract

90 Background: Racial and ethnic minorities remain under-represented in cancer clinical trials. Strategies to improve access and participation of diverse populations in clinical trials is therefore a key step to improve outcomes and eliminate disparities. Methods: Parkland Health (PH) is the safety-net system for Dallas County, Texas, and is affiliated with the UT Southwestern/Harold C. Simmons Comprehensive Cancer Center (SCCC). Trial operations at PH is mainly supported by a dedicated team of SCCC research coordinators. Interventions employed to increase minority access and accruals were focused on optimizing the portfolio, increasing provider awareness, and enhanced screening. A bilingual research patient navigator was also added to the research team to improve patient education and engagement. Transportation and childcare assistance are routinely provided for patients at PH. Accrual data for 2021, compared to 2017-2020, is presented here. Results: The majority (73%) of breast cancer patients at PH are uninsured and 88% belong to racial/ethnic minorities (57% Hispanics, 31% Blacks). Of the 15 therapeutic breast cancer trials open at SCCC in 2021, 12 (80%) were open at PH. The PH breast cancer trial portfolio included 4 cooperative group, 5 industry-sponsored (ISTs), and 3 investigator-initiated studies (IITs). Four trials were in metastatic setting and 8 were in curative intent setting. Four trials required a genomic biomarker. Forty-three patients were enrolled in therapeutic trials at PH in 2021. This represents 10.3% (43/418) of new cases during the same time period. Thirty-two were enrolled in cooperative group studies, 10 in IITs, and 1 in ISTs. The majority (93%) of the trial participants belonged to under-represented minorities. Number of trial participants in 2021 increased by 48% compared to the best year in the past 5 years (29 patients enrolled in 2018). Conclusions: Collaboration between academic institutions and safety-net systems presents a unique opportunity to provide clinical trial options to under-represented minorities. In this setting, interventions to improve trial portfolio, provider awareness, screening process, and patient education, as well as addition of a patient research navigator resulted in a significant increase in the number of minority participants in breast cancer trials at our safety-net hospital.
